The Thomas Viaduct - Elkridge end of the bridge 1970.

The Thomas Viaduct utilizes Roman-style stone arches using locally mined granite. The bridge is made up of 8 spans totaling 612 feet in length and is approximately 26 feet wide and 59 feet high from water level to the base of the track rails. It is built on a 4 degree curve which is achieved by building the piers in a wedge-shaped manner.
The Thomas Viaduct was designed by Benjamin Henry Latrobe II, then B&O's assistant engineer and who later became their chief engineer. Many at the time doubted whether Latrobe's design could even support itself much less the 6-7 ton locomotives being used at the time so they nicknamed the bridge "Latrobe's Folly".
Benjamin Latrobe reportedly suffered from insomnia and nervous disorders as he designed and oversaw construction of the bridge including shortness of breath, fainting and indigestion. Conventional treatments of the day included bleeding, cupping, purging, and drinking turpentine! Morphine and laudanum were commonly used for insomnia.
This is a lithograph from 1835 by Thomas Campbell. It was done the
same year that the Thomas Viaduct construction was completed so this
gives you a snapshot of how the area looked when the bridge was opened.
The Builders Monument can be seen at right on the Relay end and the 2-
flight staircase is barely visible on the left at the Elkridge end of the bridge.

Construction began on July 4th, 1833 and the bridge was officially completed on July 4th, 1835 at a cost of approximately $200,000. Over 600 stone masons and free black men worked on the bridge and set up a camp on the Patapsco flats just downstream from the bridge site. Locally mined granite from Ellicott's Mills was shipped via the Old Main Line on railroad cars and delivered right to the construction site.
The bridge was named after Philip E. Thomas who was the first president of the Baltimore and Ohio Railroad (B&O). A 15 foot tall obelisk stands today on the Relay end of the bridge, designating government and railroad officials connected to the project.
Today the bridge carries 200 ton diesel locomotives and heavy freight traffic on a daily basis. The Thomas Viaduct has been in service, without interruption, since the day that it was opened in 1835. It survived the great flood of 1868 as well as Hurricane Agnes in 1972, two floods that wiped out the Patapsco Valley and destroyed nearly everything in their path.
The Thomas Viaduct was designated a National Historic Landmark on January 28, 1964, and administratively listed on the National Register of Historic Places on October 15, 1966. The bridge has also been named a National Historic Civil Engineering Landmark by the American Society of Civil Engineers (ASCE).

**I'd like to point out an interesting fact about
the historic paintings, lithographs & photos**
You may notice that the very early pictures of the viaduct tend to make the bridge appear taller and a bit more graceful in it's overall appearance than it does today. It took me much longer than it should have to figure out why. The Patapsco River gorge has silted up significantly over the past almost 2 centuries. The soil all around the the bridge piers is a spongy coarse sand in consistency. I counted the number of granite blocks above ground level on several different bridge piers and found that they are buried anywhere from 3-4 feet to as much as over 8+ feet deep in silt compared with photos of the same piers 130 years ago.
This is nothing new though. Elkridge Landing (now the town of Elkridge) was just a thousand yards downstream from the Thomas Viaduct. Two hundred and fifty years ago Elkridge Landing was a busy colonial river port rivaling old Annapolis. The river there was as wide as 500 feet across and 20 feet deep. English ships sailed up the Patapsco river from Baltimore to pick up "hogsheads" of tobacco that were locally grown at the time. The river began to silt up due to ships dropping their ballast in the river before picking up cargo, mining and agriculture upriver, and occasional floods (known as "freshets") which finally made it impossible to navigate and the port ceased to exist.
There was a small steamboat that was able to navigate up the Patapsco river as far as the Thomas Viaduct which stopped at a wharf just below the bridge. The 1868 flood wiped-out the wharf and filled in the steam boat channel with silt.
Today, much of the river in the Elkridge/Relay area is little more than a shallow creek that couldn't accommodate anything larger than a row boat. Also worth noting is that much less water flows down the Patapsco River today due to Liberty Reservoir and its 160 foot high dam that was completed in 1954.
So if the Thomas Viaduct looks a little on the short and stubby side to you today, it actually is.

The dark line that looks like a dried up stream bed running diagonally
from the left bottom corner just below the tree tops in the foreground
looks to be the remnants of the mill race for the old Hockley Grist Mill
that ran from a small mill dam (just out of view upstream to the left)
and then under the first bridge span on the right. The mill was just
on the other side of the bridge. It burned down in 1883.

Oil on canvas by Stephens Berge ca. 1934-35. In 1930, Stephens
and his twin Henry, graduated from the Maryland Institute of Art, one
as a painter and the other a sculptor. Both worked full time at their
professions. Their father, Edward Berge, was a well-known sculptor.
The Berge brothers were good friends with Dolly Davis as well the
Bahrs. Stevens died in his late seventies ca.1986. A memorial show
for his work was held at the McDonogh School Galleries. Florence
and Leonard Bahr bought this painting then, and presented it to the
Elkridge Heritage Society - Sept. 12, 1989.

the people having a picnic next to a lone tree in the foreground and
several men fishing on the far shore. There is also a person looking
down from the bridge walkway. The walkway was installed sometime
after the 1868 flood destroyed the small foot/cart bridge shown in the
above drawing. Notice also that there still are no shrubs and only a
single tree present around the bridge 18 years after the flood. Photo

The same angle of the bridge today. The scrubby little trees that grow
all around the bridge block most of the views that were available 125
years ago. Notice that the river has shifted it's course over the years and
no longer flows under the same spans as it did in the previous picture.

line of scrubby trees behind that piling is where the fence was and
also where the guys are waving at the train next to the RR Crossing
sign. The tree line and bridge piling block the view of the Thomas
Viaduct which was clearly visible in the 1900 photo. The far road that
crosses the tracks in the previous photo is mostly still there behind the
right piling and it runs down to Levering Avenue. The other road crossing
in that photo came down a hill that is out of the picture at far left. It
is still there but is little more than a wide trail going up the hill now.
